BREAKDOWN OF DIODE:

When the reverse voltage applied across diode becomes greater than the breakdown voltage, then the diode breaks down and very high current starts flowing in the circuit. There are generally two types of breakdowns in a diode:

  1. Zener breakdown
  2. Avalanche breakdown

And based on the above classifications of breakdown of diode, we have the two special types of diode as

  1. Zener Diode
  2. Avalanche Diode

The difference between the Zener Diode and avalanche Diode is the doping level. The doping level of Zener diode is more than avalanche diode or we can say diodes which have higher doping level undergo Zener breakdown when reverse bias voltage is increased while diodes with lesser doping level undergo Avalanche breakdown.
